Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an emulsifying and dispersing composition, and more particularly to an emulsifying and dispersing composition for fixing natural squalene or squalane to fiber materials with good durability. It is.

[Prior art and its challenges] Natural squalene or squalane made from deep-sea shark liver oil, especially squalane produced by hydrogenating normal squalene, was known for its thermal stability,
It was used as an engine oil due to its lubricating properties, and after the war, its use as a base material for cosmetics was developed due to its permeability to the skin, spreadability, good affinity, and physiological inertness, and it is used in all kinds of cosmetics. Used as an oily raw material.

It also helps the absorption of drugs into the skin, so it can be used in pharmaceutical ointments,
It is used in suppositories, skin treatments, etc.

It is also used as a mold release agent, special lubricant, etc.

As mentioned above, natural squalene or squalane's properties such as heat resistance, lubricity, permeability, and physiological inertness can be utilized to create textile materials for baby products such as diaper covers and disposable diapers, underwear, innerwear, etc. When used as a component of a processing agent, even when treated with these individual emulsified dispersions,
It has almost no durability such as home washing resistance or dry cleaning resistance, and it is necessary to fix natural squalene or squalane to the fiber material with good durability.

[Means for Solving the Problems] Therefore, an object of the present invention is to provide an emulsifying and dispersing agent that is composed of natural squalene or squalane and a functional group-containing compound and is capable of fixing natural squalene or squalane to fiber materials with good durability. shall be.

Durability: Cotton broadcloth was treated using an emulsion composition prepared in the proportions shown in Table 1, and its durability was measured. The results are shown in Table 1.

For the durability evaluation evaluation method, a sample of 100% cotton broadcloth (scouring and drifting) was used, and the processing conditions were as follows:
Padding (weight pickup 75%) and 100
Drying was performed at 160° C. for 3 minutes, and then heat treatment was performed at 160° C. for 2 minutes.

The processed fabric was washed and dry cleaned at home, and the difference in texture between the processed fabric and the washed fabric was evaluated by handling.
